I'll have to agree with SkyWhale; the horse stance opener is used quite often by many replay makers. However, coming up with openers is hard and I understand that. They're a pain to come up with.
Anyways, the kick to uke's core was aight, I don't see any way to improve that kick or make it any powerful. But, if you want a harder and stronger hit, I'd suggest position yourself lower to the ground, it'll give you more options and lead into a lot more powerful hits.
However, you did lead into a great maneuver after the kick, making your rotational momentum carry on, which was pretty neat.
The boom kick was pretty nice, nothing too different from what I've seen. Also, nice landing.
You've got good knowledge on mid-air balancing and flowing your movements together nicely. Right now, I'd just say you need to work on making more stylish, or fast-paced replays.
